SPI top end gasket sets contain high performance reed and base gaskets plus intake exhaust gaskets for a complete cylinder rebuild. * Does not include intake exhaust gaskets

SPI gaskets are manufactured to oe-specs, which means no trimming or fitment issues. Materials are explicitly selected for their temperature, oil, fuel, and coolant-resistant qualities as well as tested using ASTM standards. Each design is evaluated against rigid quality-control standards to ensure each set meets or exceeds OE performance.
